Wan 3.0 Prime

POST https://api.beatapi.io/v1/videos/tasks

The priority render tier of Wan 3.0 — the same 2–30 second output at the same price, served from the faster queue.

Supported modes

Async flow: Create the task, save data.id, then poll the Task with GET /v1/tasks/{task_id}. On succeeded, read data.output.media. On failed, read data.error_code and data.error_message, then follow the error and retry policy.

Using a local file? upload a local input first and pass the returned data.url.
